Yes, but…
A package can only be insured for the amount it’s declared as. So if a shipper sends you a PS5 and says it’s worth $5, and that package is lost or destroyed, the insurance will only cough up $5. And it’s the receiver that’s fucked, not the merchant.
I’ve gotten tons of packages over the over that were “USB accessory” with a value of $1.05. It was all kinds of shit worth under 5 bucks. Shipper being lazy because it didn’t matter. But when you go over that, they have always been more accurate about what they put on the label in my experience.

Last time I looked into this the answer was no - it’s a permanent chemical change you can’t heal or stop or cover.
The best thing I’ve found was to keep using alcohol wipes to scrape away the gooey top surface every once in a while. ☹️
